WRINGER Filed Dec. 2, 1931 INVENTOR. Edward Engel,

ATTORNEYS and for the reception of a bearing Patented June 27, 1933 UNITED STATES PATENT OFFICE ING CORPORATION, OF SALEM,

OHIO, A bORPORATION OF NEW YORK WRIN'GEB Application filed December 2, 1931.

The object of my invention is to produce an improved mechanism by means of wh ch the upper and lower rollers may be readily associated and dissociated.

The accompanying drawing illustrates my invention in an embodiment adapted for household use.

Fig. 1 is a vertical axial section in partial side elevation;

Fig. 2 is an end elevation with portions of the end walls of the base andcross-head broken away to show internal parts; and

Fig. 3 is an elevation of one of the connector plates.

In the drawing 10 indicates a main frame or base, conveniently formed of sheet metal, and comprising hollow end standards 11 open at their upper ends, oppositely extending aprons 12, guard wings 13, and an intermediate trough 14 perforated in its bottom at 15.

Each standard guide-way for the reception and support 0 a; bearing block 16 for the lower roller 17 block 18 lower end is provided with a vertica for the upper roller 19. At its each guide way is provided with an en plate 20 to hold block 16 against-outward axial displacement.

The above-described construction is wellknown in the art and, in detail,.may be varied through a wide range.

The guard wings 13 are interiors communicate with the lower interior of the interposed end standard 11 and arranged therein is a transversely arranged leaf spring 25 the ends of which engage abutments 26 within the base.

A cross-head 21, conveniently formedof sheet-metal, is so formed and proportioned as to sleeve slightly over the upper ends of standards 11. A plate 22, carried by the cross-head, serves to prevent outward axial displacement of bearing block 18, and a plate 23, also carried by the cross-head, overlies the block 18 and serves as an abutment against lateral displacement of the upper roller.

F J ournaled in the end walls of cross-head 21 are two short rock-shafts 31, 31, the inner f 34 under the action 1 of springs 25 on hollow and their Serial No. 578,454.

ends of which project into the interior of the cross-head.

Nonrotatively secured to the outer ends of shafts 31 are the ends of a U-shaped lever 32. Non-rotatively secured to the inner end of each of shafts 31 is a crank arm 33, to the outer end of each of which is pivoted, at 33, the upper end of a connector plate 34 perforated at 35 to permit the shaft of the lower roller 17 to pass therethrough without interfering with vertical reciprocation of the connector plate.

The lower end of plate 34 is provided with a foot 34 in which is threaded a vertically adjustable pin 36, the upper end of which underlies the middle of the adjacent spring 25. Pin 36 may be held in its vertical adjustment by a check-nut 36'. A portion 37, at the lower end of plate 34, is outturned and overlies a projection 38 carried by the base 1 so as to limit downward movement of plate of spring 25.

Crank arms 33, with their connector plates 34 form toggles which, when the crank arms are placed vertically,

shafts 31.

When lever 32 is swung to its medial vertical position the connector plates 34 are drawn upwardly so as to stress springs 25 and urge the cross-head downwardly upon the bearing blocks 18 of the upper roller 19 with a desired initial pressure. Insertion of material between the rollers will cause upward lateral displacement of the upper roller and a further stressing of springs 25.

Slight displacement of lever 32 from its medial position permits springs 25 to exert arotative force thereon so that it will be quickly snapped to one extreme or the other of its movement and the upper roller will thus be instantly relieved from spring pressure.

When lever 32 is in either extreme osition an upward swinging of the crossead will cause an upward swinging of the crank arms 33 about their pivotal connections 33' so that the cross-head maybe turned upside down thereby withdrawing the upper roller and exposing it for cleansing or withdrawal from the cross-head.
